CLEVIS.

SPECIFICATION forming part of Letters Patent No. 443,650, dated December30, 1890. Applica i n fi November 23, 1889. Serial No. 331,313.(No'modehi To all whom it may concern:

Be it known that I, JOHN DUNCAN, a citizen of the United States,residing at Shedds, in the county of Linn and State of Oregon, haveinvented a new and useful Clevis, of which the following is aspecification.

My invention relates to improvements in clevises; and it consists incertain novel features hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a perspective view of myimproved clevis. Fig. 2 is a side view of the same. Fig. 3 is a planview showing it arranged to permit the removal of the clevis-pin.

The clevis-bodyA is of the usual U -shaped formation, and is provided inits ends with the openings B, through which the clevis-pin O isinserted. The opening B in the upper side of the clevis-body has a notchD in one side, and the clevis-pin is provided with a log E, which isadapted to pass through said notch and engage under the upper arm of theclevis-body. A leaf-spring F is secured rigidly to the upper end of theclevis-pin at right angles to the lug E and is tapered toward its freeend, as clearly shown. This spring is adapted to engage between the lugsG on the upper side of the clevis-body, and thereby lock the clevis-pinin its place.

In practice the body of the clevis is passed over the link or lap-ring,after which the clevis-pin is inserted through the openings in the endsof said body, so as to engage the said link or ring, and it is thenturned so that the end of the spring will slip between the lugs G, asclearly shown. The pin will thus be securely locked in the clevis-body,so that it will be effectually prevented from acoidental displacement.The lug on the clevispin engages against the inner side of theclevis-body, and thereby prevents endwise movement of the pin, while thespring fitting between the lugs on the body prevents rotation of thepin, so that it is impossible for the pin to be removed until properlymanipulated by the operator.

The device is very simple and its advant-ages'are thought to be obvious.

Having thus described my invention, what I claim, and desire to secureby Letters Patcut, is-

The improved clevis, consisting of thebody having openings in its ends,one of said openings having a radial notch and the body being furtherprovided with the lugs G on its upper side, the clevis-pin insertedthrough the openings and having a lug adapted to pass through the radialnotch, and the spring secured rigidly to the clevis-pin and adapted toengage between the lugs G, as set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.

JOHN DUNCAN.
